 Because it's basically, with simple English, a locked-on rotating object. They call it synchronous. So the mystery of the far side of the moon is just being unraveled with this interesting series of Chinese spacecraft to the moon. I hear what you're saying, and I understand the word synchronous, but I still don't understand why we don't see the far side of the moon. It's just mind-boggling. Is any other moon in the solar system like that?
